Embodiment 1
[0032] A buried tube type bubbling bed direct carbon fuel cell, which includes a bubbling bed 5, 16 dead-tube solid oxide fuel cell cells 8 with an anode on the outside and a cathode on the inside, and an air distribution plate 9 with a diameter of 5mm ~50μm powdered solid carbon fuel—graphite 4 and air supply device 15;
[0033] As shown in Fig. 2, Fig. 2 is a schematic diagram of the structure of the parallel buried tube type bubbling bed in Embodiment 1. The air distribution plate 9 is installed at the bottom of the bubbling bed 5, and 16 dead-pipe solid oxide fuel cell cells 8 are inserted into the bubbling bed 5 along the horizontal direction, and the open ends of the dead-pipe solid oxide fuel cell cells 8 are located in the bubbling bed. Outside the bubble bed 5, the closed end is located inside the bubble bed 5, and the joint between the bubble bed 5 and the solid oxide fuel cell unit 8 is sealed with high-temperature ceramic glue 10, and the interface structure is sho...
